Ali, 71, has suffered with Parkinson's disease since 1984. His heath has declined as he has aged, but Rahman Ali said his brother's health got progressively worse in recent months. Ali no longer recognizes him, Rahman said.

A three-time world heavyweight champion, Ali last fought in 1981, losing to Trevor Berbick. He finished with a career record of 56-5.
